Abstract

The coupling bolt 5 of the proposed trailer bolt coupling is moved upwards into its release position by actuating a hand-operated hydraulic pump 35. For this purpose, it has a blind hole which serves as a hydraulic cylinder space 15 and into which a rigidly attached piston rod 19 with piston 17 projects, the actuation pressure of the hydraulic fluid being introduced into the rod space of the hydraulic cylinder through a hole 21 which extends in the piston rod and opens above the piston. A release valve 55 which is triggered by the drawbar rod of a trailer when it is being hitched allows the hydraulic fluid to flow off again so that the coupling bolt moves back down again to its coupled position under the effect of a coupling spring 25. <IMAGE>
